Star Cement Ltd Q3 FY2025 Concall Summary

Key Takeaways

• Earnings miss on one-off stabilization costs: PAT fell sharply to ₹9 crores from ₹74 crores, and EBITDA dropped to ₹107 crores, as ~₹40 crores in one-off costs from new plant stabilization and forced clinker purchases hit the quarter.
• Volume growth story intact: Cement sales grew ~10% YoY to 10.60 lakh tons, driven by the Northeast market, and management targets 12-15% volume growth in FY26.
• New capacity now stabilizing: The new clinker line is utilizing ~70% capacity day-to-day, and management states no further clinker purchases will be needed, removing a key margin drag.
• Trade mix shift underway: Trade share dropped to 51% from ~90% as new capacity pushed the company into non-trade infrastructure markets, a structural shift with lower realizations that management frames as a volume play.
• What to watch next quarter: Whether the guided ~10% Q4 volume growth and ₹225-230 crores full-year EBITDA materialize now that one-off costs are behind, and whether Northeast pricing holds stable as guided.

Q3 Miss: The One-Off Cost Story

• Clinker line stabilization delay: The new clinkerization unit at Lumshnong took longer than expected to stabilize, forcing the company to purchase ~1.5 lakh tons of clinker from outside at a cost of ~₹30 crores, a margin hit that management says is now resolved.
• Maintenance shutdown costs: An additional ~₹10 crores in shutdown-related expenses compounded the EBITDA drag, taking the total one-off impact to ~₹40 crores for the quarter.
• Clinker production drop: Clinker production fell to 6.42 lakh tons from 7.37 lakh tons YoY, constrained by both the new line stabilization and road repair work on the Silchar-Khliehriat highway that limited transport vehicle availability.
• EBITDA per ton compressed: Realized EBITDA fell to ₹1,000/ton from ₹1,576/ton YoY, a compression management attributes entirely to the one-off factors rather than structural margin deterioration.
• Incentive income lower: Incentives came in at ₹43 crores versus the ₹50 crores+ expected in Q4, held back by the volume constraint from the clinkerization unit stabilization.

Dilip Agarwal: "Given the issues that we faced in Q3 in terms of stabilization time of our new clinkerization unit and then followed by some purchase of clinker from outside, otherwise our Q3 numbers would have been better."

Volume Growth & Demand Drivers

• Northeast drives the bus: Northeast volumes grew to 8.30 lakh tons from 7.32 lakh tons YoY, while outside Northeast saw slight degrowth to 2.31 lakh tons from 2.38 lakh tons, reinforcing the core market's primacy.
• FY26 growth ambition: Management targets 12-15% volume growth next year, building on an expected FY25 close of ~0.47 crore tons, implying ~0.54-0.55 crore tons in FY26.
• Infrastructure tailwind: Central government budget allocation for Northeast infrastructure development is projected at ₹1 lakh crores, and management has planned the Jorhat and Silchar expansions specifically to capture this demand.
• Seasonal capacity logic: Even at ~70% annual utilization, the company needs surplus capacity to serve peak-season demand from October through April, justifying the new grinding and clinker units.
• Siliguri underutilization persists: Capacity utilization at Siliguri remains ~45% because outside Northeast markets have not grown, clinker constraints existed, and Northeast realizations are simply better, though some improvement is expected in Q4.

Capacity Expansion & Project Pipeline

• WHR system imminent: A 12 MW Waste Heat Recovery system will be operational in Q4 FY25, adding cost efficiency to the power mix.
• AAC block project near completion: The AAC block project is in advanced stages and should be commissioned in Q4 FY25, barring minor finishing work.
• Silchar grinding unit: Commissioning targeted by December 2025 or within FY26, adding grinding capacity in a catchment area with growing infrastructure activity.
• Jorhat expansion on track: The FY27 timeline remains unchanged, with full capex to be incurred over the next 1.5 to 2 years; the location offers a ~300 km lead distance advantage from Guwahati into Upper Assam.
• Rajasthan foray progressing: The company won a bid for Rajasthan mines with a deposit of ~6.5 crore tons; exploration and testing are underway, and land acquisition is in process, though no timeline has been committed.
• 2 crore tons by FY30 target stands: Management reaffirmed the ambition, noting six full years remain to conceive, start, and complete the required projects, with execution experience from recent rollouts providing confidence.

Trade Mix & Market Strategy

• Non-trade pivot is deliberate: Trade share fell to 51% from a historical 89-90% because the new Guwahati grinding unit and clinker line increased capacity, leading management to test non-trade infrastructure markets it previously avoided due to lower realizations.
• Prime focus remains Northeast: Despite the non-trade push, management stated the Northeast market will remain the dominant share of the overall pie, with outside Northeast focus only once prices improve and operations are streamlined.
• Outside Northeast pricing under pressure: Prices in West Bengal and Bihar have taken a beating alongside volume degrowth, though Bihar saw increases in November/December with full impact expected in Q4.
• Freight cost management: The company added 120 vehicles for the new clinker plant, and operating its own fleet provides bargaining leverage with transporters, helping contain freight costs even during the year-end pressure period.

Competitive Dynamics & Barriers

• Dalmia entry downplayed: When asked about Dalmia's new kiln starting early next year and potential pricing erosion, management deflected, stating they do not expect price discipline to break and that the discussion is premature until Dalmia is actually in the market.
• Consolidation unlikely in Northeast: Management sees no opportunity for buying out smaller plants, most of which are sub-0.1 crore tons, and noted that new entrants face significant hurdles in land acquisition and local issues.
• Long timeline for new capacity: Even if a new entrant overcomes all hurdles, management estimates a minimum 4-5 year timeline to put up a new plant, concluding that nothing big is expected in the immediate or near future in the Northeast.

Management: "If you go and put a new plant, if you are able to do it considering all the hurdles also, then also minimum four to five years is the minimum timeline. So, I do not think that in the immediate future or near future something big is going to happen in Northeast."
